Knee: The knee is a joint which has three parts. The thigh bone (the femur) meets the large shin bone (the tibia) to form the main knee joint. This joint has an inner (medial) and an outer (lateral) compartment. The kneecap (the patella) joins the femur to form a third joint, called the patellofemoral joint. The patella protects the front of the knee joint.
Two major areas in the brain affected by autism are Wernicke's Area and Broca's Area (Carlson, 1999). Some other areas studied shown to be affected in autistic patients include the limbic system, cerebellum and association cortex.
The amygdala is an important part of the brain, which assists in responses of fear and pleasure. The abnormal working of the amygdaloid body can lead to various clinical conditions including developmental delay, depression, anxiety, and autism.
